.macro goto_if_lt dest:req @ LESS THAN

@ Allows 'compare' followed by a conditional goto/call to be combined into a single statement.
@ The following are examples of the two acceptable formats this facilitates:
@ compare VAR_RESULT, TRUE
@ goto_if_eq MyScript
@ - or -
@ goto_if_eq VAR_RESULT, TRUE, MyScript
@
@ The first two arguments to this macro are the base command, e.g. 'goto_if 1' for goto_if_eq.
@ The remaining arguments 'a, b, c' depend on the format:
@ For a single statement, 'a' and 'b' are the values to compare and 'c' is the destination pointer.
@ For a statement preceded by a compare, 'a' is the destination pointer and 'b/c' are not provided.
